Talus Replacement Registry

Avascular necrosis of the talus is a difficult problem to manage, especially in the young and healthy. The only option, historically, has been a talectomy and hindfoot fusion. While this is a viable option, it is not without its morbidity. Arthritis of surrounding joints is common, occurring anywhere from 1-10 years after the procedure. This is especially true in younger patients, where loss of motion can be life altering both physically and mentally. The search for alternatives has been limited. Recently, 3D printing has become more ubiquitous and affordable and newer medical alternatives have arisen thanks to this technology. The 3D custom talus is relatively new in the orthopaedic community, but has been used at several centers with good success. It has been shown to re-establish the normal alignment of the foot, preserve motion (with some achieving almost physiologic motion), and allow for almost normal ambulation. However, the data is still limited and further study is necessary. Our facility was recently approved to perform this procedure. Our hypothesis is that custom 3D printed talar body replacements, either used alone or with total ankle replacements, will maintain physiologic motion, have no difference in complications when compared to hindfoot fusions with allograft, lead to good outcome scores and patient satisfaction scores. Patients diagnosed with avascular necrosis of the talus who have already decided to undergo a procedure involving a 3D custom talus as part…
